Kragman, are you shooting from a bench restaurant or offhand?
You probably may know better than me, but for the good of the order, I'll share how I test pellets. When I'm testing pellets, I want to take away as many variables as possible, so I shoot from a bench. I start with the rifle balanced on a sandbag so that it is lined up on target without me even touching it. I have one of those Monkey bags with the three comparments. Then I get into a very relaxed position where the gun is barely touching my shoulder pocket and my trigger hand is only lightly touching the grip. Most of the time, my thumb is up in the air. Sometimes with springers you have to figure out the best hold, but I always start with this balanced hold. Finally, I close my eyes, take a few breaths, and relax. If I open my eyes, and I'm not on target, I adjust my chair, right elbow position on the shooting table, etc. until I am right on when I open my eyes. Then I take a breath, take up the first stage, let my breath out half way, and shoot. Then I try to do it all over again exactly the same way. I'm no expert, it's just what I do. I shoot a few groups of ten shots each for each pellet and average the results. In the example I gave above, I went the extra mile and made a graph that showed the accuracy on the y axis and the cost per pellet on the y axis. You can really see which pellets give you the most accuracy for the value. The pellets that graph closest to the bottom left corner are the most accurate for the money.
Then you can lay in a supply of the best pellet so they all come from the same lot.
